Hi, I've connected the battery up, replaced the main fuse and as soon as I go to close the casing where the fuse is it pops. I did have a dodgy connection on the battery but this is now sorted. Any ideas? It's a cb400 super four vetec 1996 model

Its obvious you have a dead short somewhere,,,sounds like when you put pressure on fuse door,,it is pushing a bare wire onto the frame and blowing the fuse,,,check any connections you have installed or removed,,even under the fuse holder,,,make sure you have the right size fuse to handle the load..

Most main fuses are located close to the positive battery cable and in some cases attached directly to the positive cable located in a plastic box with a cover. There may also be a fusable link used for a main fuse which will connect to the starter

Hi, Sam you have a dead short which is usually the easiest to find. Using a test light connected to the hot side of the blown fuse holder, start probing the wire leaving the fuse holder about an inch away the test light should illuminate, keep probing towards the ignition switch until the test light no longer illuminates you are now very close to the short.

Usually a bad regulator will only cause problems with charging...Sounds like you've got a short somewhere in the wiring...I'd start by checking the ignition switch wiring and the connections going into the fuse box.

It will most likely be a poor earth issue, make sure the earth lead between the battery and the body is good and clean and check the one between the body and motor. Poor earth connections cause excessive current draw and will blow fuses.

Start by checking the fuses and then the battery connections, this sounds like a fuse poped maybe a main fuse, if its a fuse then replace the fuse if it pops again then theres a dead short somewhere, these are famous for bad starters and starter relays going bad, so see when fuse pops again if its when key is turned on or when you try to crank the motor, if its when cranking then its mostlikely the relay or starter, this main fuses would be in the engine compartment fuses box.

Hi Anonymous, you have a hard/dead short that should be easy to find generally they are the easiest. Time to get out your test light and connect it to the power side of the, circuit breaker or the blown fuse receiver, start by tracking the out bound wire towards the ignition switch and beyond if necessary, when the test light quits lighting you are very close to your short.

Every time i have this prob i've blown that channel. In my case i,ve had dodgy connections to my speakers and if it is operating with high voltage rails they don't take much to blow. Take off cover and you will no doubt find fuses somewhere blown. If it has come from speakers you prob done the amp but if not you might be lucky and just have to replace a single fuse or so.Good luck,Paul
